User Evaluation Serendipity

A nice bit of unofficial user research just thrown into my lap. A few days ago, I created an automatic photo blog to store the pictures from the LightScribe App prototype. I put a few existing pictures on it to test the setup. I was very surprised when it started raining ‘likes’! Hint: go to the bottom of the post and click on the star 🙂

At first it was just nice to feel appreciated, but then I decided to check out which picture had the most likes. And it turned out to be exactly the one I had already chosen to be the basis of my GUI design! So have a look and see if you agree.

Automatic Photoblog: test 3

In order to not keep bothering you with each and every picture I take, I created a new blog especially for the purpose of automatic photo blogging:

lightscribeblog.wordpress.com

Stop by some time!

Automatic Photoblog: test 2

Aha. Now I’ve set up a nice little Automator sequence, but it appears that when I remove a picture from that folder, it mails an empty blog post. I really need to insert a bit that stops the actions if there are no files. Luckily I found this great little download that’s aptly called ‘Stop if Input is Empty’

Now my workflow looks like this:

Combined with the Eye-Fi SD card in my camera (read about it in this post), it really should be snap and post in one go!

Automatic Photoblog: test 1

So this is me trying to set up a feature where I can automatically post pictures to my blog. When my LightScribe prototype will be finished, I can use this to keep track of the results made with the prototype.

Step 1: Post by email.

Slow Shutter Cam

Today I found this great app: Slow Shutter Cam for iPhone. What I like is that although the functionality is quite simple (you can adjust the shutter time), it has positive reviews and people are also using it for light painting.

Good to see that apparently there is a need for this kind of app!

A LightScribe Story

Imagine you are a 15-year-old boy and bored to no end. Finally, the school bell rings and you are done for the day. Usually, you would hang out in the nearby park with friends, doing nothing really. But ever since some of your friends introduced you to it, you are often using the LightScribe app, like today. When you see your friends, you all whip out your smartphones and start the app. The app sees all available LightScribers in a nearby radius, so you can easily select your friends’ group from the list. With some laughs and jokes, the best location is picked. Perhaps when it gets darker outside, you will move to the park, but for now, the decision falls to the bike shed.

The app picks one random cell to be the ‘photographer’. The other participating smartphones are designated ‘light sources’. You are picked to be one of the light sources, and the screen of your cell Continue reading

A Recap of Two User Evaluation Sessions

Finally, it’s here! A condensed video showing the most interesting outcomes of two User Evaluation sessions about the Light Scribing concept.

If you would play this video on your smartphone while Lightscribing, I am sure it would give a nice effect.


And why not program the phone to generate a random color sequence, like the screensaver this video was taken from?

Second User Evaluation of Light Scribing

One week after the first user evaluation, we held another evaluation session. One reason to do this was to see if the technique would still be interesting after some time, and if users would be prepared to keep using it.

All four students in this project were present, and some had prepared special hand-held lights to use. On top of that we had the use of a more advanced camera that could do longer shutter times. Three of the four original users were present as well.
